ENAIVIELED ORNAMENT.

SPECIFICATION forming part of Letters Patent N o. 793,659, dated July 4, 1905,

Application filed November 19, 1904. Serial No. 233,414.

To all whom it may concern.'

Be it known that I, OTTO L. HEINTZ, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Enameled Ornaments, of which the'following is a speciiication.

This invention relates to a method of making enameled ornaments, and has the object to produce high-grade goods of this character in an expeditious manner and at comparatively small cost.

In the accompanying drawings, Figure 1 is a face view of an enameled ornament produced according to my improved method. Fig. 2 is a sectional View showing the first steps of my method. Fig. 3 is asimilar view illustrating the means whereby the iinal steps of my method are effected, the section of the ornament being taken in line 3 3, Fig. l.

Similar letters of reference indicate corresponding parts in the several Views.

The body or base A of the ornament may be of any suitable form and material, that shown in the drawings consisting of a rectangular sheet of metal, such as copper. Upon its face or front side the body has depressed plain surfaces 'B and enameled surfaces C, which are elevated or in relief above the plain surfaces, these surfaces being disposed to produce the desired ornamentation.

ln producing this enameled ornament a coat of enamel, preferably in the form of paste, is first applied to the face or front side of the body, as shown at c in Fig. 2. The same is then heated at a low temperature for drying the enamel and causing the same to stick or cling to the body. In practice it has been found that a temperature of about 100O is sufficient to produce the required drying and sticking of the enamel. Those parts of the enamel above those parts of the body which are intended to be the plain or depressed surfaces or the ornament are now removed, leaving the remainder of the enamel standing in relief and elevated above the plain surfaces. The removal of the enamel Where desired is preferably effected by placing a stencil D over the coat of .enamel and delivering a blast of sand against the front side of the same,where by those parts of the enamel which are eX- posed through the ornamental openings d of the stencil Will be cut away, while those parts of the enamel I covered by the solid parts of the stencil will be protected from the cutting effect of the sand and will remain standing, as shown in Fig. 3. After the enamel on the body has been thus cut into ornamental form the same is again heated, but at a high temperature, so as to thoroughlymelt and bake or harden the same and permit of its being handled freely without danger of cracking. About 1,300O of heat has been found a suliiciently high temperature to effect the required hardening of the enamel.

My improved method is particularly Well suited for producing panels for use in screens, fancy boxes, toilet articles, and jewelry; but the same is capable of use for all purposes where enamel ornaments in relief are desired.

I claim as my invention- 1. The herein-described method of producing enameled ornaments which consists in applying a coat of enamel on a body, then heating the same at a low temperature for drying the enamel and causing the same to stick to the body, then cutting' away parts of the enamel for producing ornamentation, and then heating the same at a high temperature for melting and hardening the enamel, substantially as set forth.

2. The herein-described method of producing enameled ornaments which consists in applying a coat of enamel paste on a metallic body, then heating the same at a low temperature for drying the enamel and causing the same to stick to the body, then cutting away parts of the enamel for producing ornamentation by delivering a sand-blast against the coat of enamel through a stencil, and then heating the same at a high temperature for melting and hardening the enamel, substantially as set forth.

fitness my hand this 14th day of November, 1904.
